Definitions

  • thermoplastic, smooth and/or corrugated tile type board based on new polymers or polymeric waste, pure and or composed of various plastics, whether or not chemically compatible, with or without fillers, natural/industrial/mineral/animal, individually and/or combined up to 80% by lamination process, in single or multilayer form, using various melting process mechanisms; and also allowing the interlayer and or superficial introduction of bodies, rigid or flexible, for the purpose of structural reinforcement and or surface finishing.
  • Lamination is a plastic forming process that involves the passage of a body between two cylinders so that its thickness decreases, while the width and length of the body are proportionally increased.
  • the polymer lamination process is known, for example, the document FR9700305 describes a process for the manufacture of thermoformable sheets and/or plates from a temperature of 80 C/90 C, usable as a self-adhesive reinforcement material, characterized by the fact that: from 30 to 70% by weight of granules of low melting weight (50 C to 90 C) polymer(s) thermoformable from a temperature of 80 C-90 C with 70 to 30% by weight of melt point polymer(s) melting or higher softening in granules or in powder with a granulometry greater than about 500 ⁇ m, preferably from 500 to 1000 ⁇ m, both types of polymers being thermoplastic and fully or partially compatible, with possibly the usual additives, the mixture is extruded in low shear conditions with low temperatures of 100 to 140 C giving the mixture a pasty consistency insufficient to form a homogeneous mixture of molten polymers, after this extrusion and eventual addition of a support ( 9 , 12 ) in the extru
  • thermoplastic board production process such that the product can be fully reproduced by suitable technique, allowing full characterization of the functionality of the claimed object.
  • the descriptive part of the report is based, through a detailed and consecutive numbering, where it clarifies aspects that may be implied by the representation adopted, so as to clearly determine the intended protection.
  • FIG. 1 shows the complete production unit containing the extruder, lamination/thermofixing line, screw saw and receiving table;
  • FIG. 2 shows the extruder
  • FIG. 3 shows the lamination and hardening line
  • FIG. 4 shows the thermofixing line by plates
  • FIG. 5 shows the side cutting saw, dividing saw and haul off
  • FIG. 6 shows the completion of the process with square cutting and receiving table.
  • thermoplastic plate production process uses an extruder ( 1 ) with temperatures from 100 to 450° C., which delivers a large volume of plastic mass to the lamination line ( 2 ), where the already laminated plastic mass passes to molecular fixing line ( 3 ), through cool pressing plates, passing to the cutting line ( 4 ), through the side cutting saw and dividing saw, being the product sent to completion through the square cutting ( 5 ) and deposition on distribution table ( 6 ).
  • Plastification/gelling/melting of the mass shall be by:
  • plastification/gelling/melting can be performed by other continuous or batches plastification systems.
  • a lamination system offers plastic mass absorption from an extruder or any other continuous or batches plastification system, accumulating an important volume, thereby compensating for volumetric variation, and then forming the product via the laminator cylinder and not by flat die, in others words, it absorbs here the typical volumetric variations in waste extrusion.
  • Another innovation presented is that, throughout a multiple laminating system, it allows the recompression/hardening of the mass in order to reduce internal expansions from typical waste gases, thus allowing the production of profile up to 200 mm thickness, in width of up to 6,000 mm.
  • the project foresees the molecular fixation, in addition to the laminator cylinders, through the introduction of a cool pressing plates system, offering molecular fixing until the complete thermal stabilization of the product.
  • the production process involves inserting the gelled mass by means such as flat die ( 2 . 1 ) for pre-opening the mass into the first lamination group ( 2 . 2 ) into an accumulator ( 2 . 3 ). Ensuring the absorption of volumetric oscillations from the laminating equipment, being formed the primary profile of the final product.
  • the pre-formed mass is by hand and/or automatically moved into the second lamination group ( 2 . 4 ), where the recompressed mass, pre-hardening and gas exhaustion by compression phase ( 2 . 5 ) occur, cool plates held in between the two groups ( 2 . 6 ) to start molecular fixing.
  • the material In the second lamination group, the material automatically runs towards the next lamination groups, for hardening ( 2 . 7 ), always intermediated by cool pressing plates ( 2 . 8 and 2 . 9 ), until it reaches a molecular fixing ( 2 . 10 ) point ensuring the final geometry desired.
  • a first puller ( 3 . 1 ) up to 50,000 kg/f pulls the formed product ( 3 . 2 ), and sends it to a group of pressing boards ( 3 . 3 ), until final molecular fixing desired.
  • the produced board ( 3 . 2 ) is cut to define desired width through the side cutting saw ( 4 . 1 ), divided lengthwise accordingly profiles width and number definition, automatic lengthwise cut, through the dividing saw ( 4 . 2 ), being the material pulled by a second puller ( 4 . 3 ), where this ready material is cut by the square cutting saw ( 5 ) and automatically sent to a reception table ( 6 ).
  • Additional inline surface finishing options such as texturizing, machining, polishing, grinding, brushing, printing, grooving, painting and hot stamping.
